REVERSIBLE ROTARY i To all whom it may concern V Be it known that I, CARL S. ROSE, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented a new and useful Improvement in Reversible Rotary Engines, of which the following is a specification.

My invention relates to reversible rotary engines wherein a rotatable member having a plurallty of radially disposed rotating bores closed at the outer ends thereof, by

means of a suitable stationary casing having channels arranged to supply energy to i the outer ends of the bores, operates inconjunction with a plurality of pistons slidably mounted within the bores and operatively connected to a stationary shaft seteccentric with the rotatable memberyand the objects of my invention are first, to provide an innproved unit for generating power that shall be simple of operation and cheap of construction; second,-toprovide a device of the character described wherein the pistons and bores, orcylinders shall be rotated thereby eliminating the necessityfor a fly-wheel or equivalent; third, to provide improved means for regulating "the supply of energy to the bores; and fourth, to provide a rotary engine of the character described thatmay be easily reversible. l accomplishthese 'sev-' eral features by means 0f] the device disclosed in the drawings forming a part of the present specification,wherein like characters of reference designate similar parts'throughout the specification and drawings, and in Figure 1 is a tional view of the device disclosing the an rangement of the bores and the pistons slid-,

ably mounted therein, the valves in the upper openings not being shown for the purpose of simplifying the drawings. Fig. 2 is a transverse vertical sectionalview of the device disclosing the manner in which the rotatable member is rotatably mounted within the casing and the manner in which the pistons are operatively connected to an eccentric stationary shaft. Fig. 3 ls'an enlarged sectional view of. a. portionlof the casing disclosing the manner in which the supply Specification of Letters Patent.

of energy from the channel is regulated by a valve. Fig. 4 is an enlarged plan view of a. valve, 1n an open position. Fig. 5 is a view similar to Fig. i but with the valve shown closed. I I

Referring to the drawings, the numeral 1 is usedto' designate a suitable frame having a, driving shaft 2 rotatably' mounted therein. To the inner'end of the shaft 2 1S rigidly securedarotatableimember 3 hav- 4L therein. mounted a PlStOIiii wh ch is operatively connected, by 'means of a, suitable connectingv rod 7 to a stationary shaft 8 set eccentric to the drive shaft 2 and the rotatable memhere-3 thereon. adapted to engage guide ring9 concentric with and secured to the stationaryshaft 8,

. the purpose. of which will hereinafter be more fully described.

A suitablecasing for the rotatable m her 3 isformed; by the circularmember'12' to which isrigidly secured an annular. ring 1 1 having two semi-circular channels 15 and 16formed therein. A plurality of radially disposed apertures 17 penetrate the channels '15 and 16 and are arranged to communicate withthe'boresa of the rotatable member 3. I

The inner ends. of the. apertures 17, except the three lowermost on each side, are-provided with a valve seat-l8 having diametrically opposed ports 19 and a pin 21. A valve 22 having an'arcuate slot28 therein adaptedto engage the pin 21, is rotatably mounted u on each valve seat'18 and is rovided with diametrically opposed ports 24: arranged to register in one position,.with the ports- 19 of the valve seats 18. Within thejouter end of each aperture l'? is secured a suitable stuiling gland 26 within which aisrota'tably Each connecting rod, 7 is mounted a valve stem 27, the lower end of" the said stem 27 being, slidably mounted within the valve 22 and'rota tably mounted within the center -'of the valve seat 18. l A spring 28 is interposed between the lower end of each stuffing gland 26 and the valve 22,; the purpose of which will fhereinafter be more fully described. A steam supply pipe 30 supplies steam or energy to the 60 ing a'rplurality of radially disposed bores 1 l/Vithin eachbore 4 is slidably channel while similar nected to the channel v16. 7 a a,

The operation of the device is as'follows:

. The valves 22 are first adjusted to regu- V s o .zlateotlieifiowof steam or other suitable energy to the bores'e adjacent tothe channel it 15,;each valve, beginning'with the lowerrotatablefmember having a plurality oframost, being-adjusted to admit more steam or other energy than the one immediately above it so that as the rotatable member 3 and the bores e l-therein move upward, the supply ofsteam' will be lessened, the steam within each bore expanding and moving'the piston 6 therein inward and the bore upward siuniltaneously- As the three lowermost ap ertures 17 are without valves and therefor admit-steam under fullpressure to the bores, 1 l as they pass the said apertures it is, evident thatthe pistons 6 within those bores will be operatingunder full pressure While the bores above Wlll be operating under the expansion plus an additional head of;v steam or energy admitted through the partly opened valves. -Asl the 'pistons'are moved inwardly by-Qthe expansmn of the steam or other suitable energy, it is evident thatthe said movement will impart a rotary movemen't to the connecting rods 7 which willref actthrough the medium of the'pistons' 6 and rotate the rotatable member 3.1As eachbore etreaches the uppermost point in the rotation of the "member 3 thepiston .6 in that i bore will be at the lower limit of its stroke;

As the-bore descendson the other. side the outward movement of the pistont; will as-' ,sist the exhaust of the steam or energy a [through the apertures 17 and the valves 'herein into the channel 16 until the bore 1 -aches the three lowermost apertures when any remaining steam will be completely exhausted'therefrom through the three lower- :most apertures 17. V The exhausted steam" will then be conducted from the casing by meansof the connection or pipe 31; If the supply of energy: is introduced through the pipe 31 instead of through-the pipe30, by

"means of-any suitable reversingvalve gear not shown; it is evident that the operation heretofore,se't forth 'will obtain except that the rotatable member 3. will-rotate in the opposite direction. vr Whilerotating in the op posite direction the exhaust steam may be dread-oily exhausted through'the valves 22 which heretoforeadmitted steam forthe reason thatfthe said valves 22 are held onto a the seats 18 by meansof the springs 28 'which will permit the valve 22 to lift and the steam to escape from the bores 4 and into the channel 15 which then becomes an exhaust instead of asupplychannel as "hereinbefore described. a

It is obvious from the which may be easilyand readily reversed by pipe 3l' is con- V foregoing that I have prov1ded an mproved rotary engine channel.
